Sticks - unfortunately, if someone brought it up at a board meeting, their eyes would glaze over and the President would say "what does that have to do with shooting trap?" Then another board member would add "or Cowboy Action Shooting?"
To be fair, the firing line is at 6600ASL and my velocity was around 1375 at 1k, so still > Mach 1.2. I input a sea level average pressure of 29.92 Hg and kept the othe environmentals the same and 1375 is about what it would be doing at 800 yds - and it would be just off mach 1 at 1k. I buy into the destabilization thing at Mach 1.2 since I'm able to observe it with 223 at 900 yards on windless days with the ballistics model starting to fall short, as well as randomly widening POIs after adjusting holdover. A 123 gr 6.5 is obviously going to transition better, but a little bit of luck does enter the equation after going below Mach 1.2....
I was going to suggest that you wheel a box of bricks out of the back on a hand truck after you close a super ultra mag rifle sale and say "your going to need these", but I guess that might impact threading and muzzle brake sales. Lol

Hunting seasons kicking off here in Maine as well. I've sold a boat load of the R700 Long Range in 300 ultra mag to green shooters watching American Sniper over and over.
It's always a treat watching them take their first shots...
Keeps my lathe going threading barrels and muzzle brakes goijnf out the door...lol
